IMPROVEMENT IN C'OIIN-PLANTIERS.

rS'pecijcation forming. part of Letters Patent No.100,032, dated February 22, 1870."

To all fwhomz't may concern: Be it known that I, GEO. D. HAWORTH, of Decatur, in the county of Maconand State of Illinois, have invented a new and Improved Corn-Planter; and I do hereby declare' that the following is a full, clear, and exact desoripf i tion thereof, which willenable those skilled in the art to make and use the' same, reference being had -to the 'accompanying draWiugs,'j

forlnin g part ofA this specification.

This invention relates to improvements iu' that class of corn-plauters wherein the valves are worked by a knotted cord stretched across the iieid, secured at cach end-aud working over themachine as it nieves back and forth .to work the valves.

The invention has for its object rst, to take up the knotted cord by the machine audlay vit over in the position for the next passage, so

that in working over the machine it willl not be drawn, as is now the case, obliquel'y to it, whereby the clogging and catching of the cord upon sticks, stones, olods, and the like 'are avoided, which now requires a person to walk in advancel .toarrange the cordg-lsecond, an arrangement of slotted arms on' a.. cross-bar, over which the cord is transferred-froin-side to side at suitable distances apart, and soconnected together by rods and to the grain-slidesv that each knot is made to produce an advance and return movement of the seeding-slides at.

the proper intervals for dropping the corn, the

whole constituting. an attachment applicable to any machine; third, an arrangement where-v by the slotted armson'which the cord acts to .give the motion to the seeding-slides are given the function of moving a. certain distance after the knots on the cord come in contact with them, before motion isimparted t'o -theseed' after more fully specified.

leach movement across the field. This bar cerries pulleys, F, at each end', 'on supportsG,

'capable of vibration, and provided with'shouljders, H, for arresting and 'holding them 'at the required position by coming into contact with;

th'epins I; K K are crotched bars, pivotedto the said bar, one near each end, and arranged' tovibrate in ,a vertical'plane. 'They are con. nected by rods L to a rocker-plate, M, pivoted centrally at N on astand, O, rising up from'v the center of the bar E, one aboveand'the other below the central pivot N. The connecting-pn'fonthe lower rod L works in a slot inthe upperend of another rockergpla'te, P,'p'ivoted at Q, and veomiected bya rod', I t, to a crank, S, of Aa shaft, '1l-,so connected 'to the handlever D that theo'scillationlof the shaft will vibrate the said handle and work `the said slides. U represents a guidegpulley, mounted on the stud O., V represents the' knottedcord, which, 4being fastened at eachen'd by pins driven into lthe ground or other` suitable means, is bythese devices made use of forvibrating the said slides, giving themback and forth movements, and is itself trans# ferred by them from one position-to anotherml as required. .l p

The knots' W-arcmade in the cord atabout twice the distances apart which the hills,v of

corn are desired to be, and the crotched plates K are placed the -same` distance as fthe-rows' apart. They arev worked back and forth -by` the knots, as follows: The -knot on the left of l'the machine, looking in the direction of the;

forward movement thereof, being drawn intothe crotch of the tilling-plate or arm on that side which is represented .in the drawingv as inclined toward the said knot, will engage with the said crotch and carry it over to the other side of the vertical line, escapingitherefrom by rising up the inclines of the crotch after tilting it; thus, owing to the connection of. one rod, L, above, andthe other below, the axis of the rocker-plate lll will tilt the crotched plate on the right toward the center, so that the same knot, when arriving at the latter crotch, will be caught in the crotch in the same way andtilted over to the right, which will throw the crotch at the left back again, to

lbe acted upon in the same way by the next Y knotand so on as long as the machine is kept in motion. I

'In order to produce the movement of the grain-slide ina shorter space of time than that required for the movement of the crotched plates, which is necessary to drop the corn quickly, the slot in the oscillating or'rockingr plate P is made wide at the top, and narrows down `by curved lines toward the bottom, so that the pin X will not act on theV walls thereof only when the rocker-plate M is near the vertical position, and then only for a short space, whereby it is allowed to move both before and after the movement of the plate l),

, without moving the latter for allowing the necessary movement of the crotched plates. The bar E and its adjuncts, and the crankshaft T, may be detachably connected to the .frame and to the handlever, or other means of operating the slide-bar O, so that the Whole form an attachment which may be used or not,

as preferred, and adapted for attachment to any machine.

i I may use other arrangements of devices in connection with the rocker-plates K and the slide C for obtaining'rnotion from the cord and imparting it to the said slide, and I do not desire to limit myself to this particular arrangement in connection with the means for trailsferring the corn;`bnt, having` thus described m y invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination of the knotted cord and the crotch `vibrating plates K, connected to therocker-plate M, and together by the rods L, when arranged for each knot to produce an advance and return movement of the said crotch plates and rocker-plates, substantially f as specified.

2. The combination of the rocker-plate M and crotch-plate P, when the-latter is arranged as specified, topermit the movementV GEO. D. HAWORTH.
